  • Publication number: 20230357542
    Abstract: The present invention relates to methods for processing plant and/or micro-organism derived cellulose materials into rheology/structuring agents. More in particular, the present invention relates to methods wherein plant and/or micro-organism derived cellulose material is co-processed with carboxycellulose. The methods of the present invention provide a variety of benefits, in terms of process efficiency and scalability as well as in relation to the properties of the materials that are obtainable using these methods. For instance, it has been found that (highly) concentrated products produced using the method of the invention are easily (re)dispersible in water and aqueous systems to regain much of the cellulose component's original rheological performance.

  • Publication number: 20220213297
    Abstract: The present invention relates to compositions comprising fibrillated cellulose and one or more nonionic cellulose ethers. Such compositions were found to be able to modify the rheology of an aqueous medium, also when the aqueous medium comprises salts and surfactants, whereby specific formulations shows desirable thixotropic thickening of the aqueous medium.
